HP 6455e Printer says it's offline yet it's hard wired with USB and wireless network. Not printing

[Msubemr786-9]

Connects and disconnects from internet. I have it on wireless and USB yet it still says offline.  Now my printer is flashing yellow on the right side, signaling ink issues but both inks are full and connected.  I am never buying HP again.  This is absolute nonsense trying to fix these issues.  The HP Smart diagnostic is a  POS and does nothing.

Hi @Msubemr786-9,

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

My sincere apologies for the inconvenience caused to you.

We'd hate for you to be stuck in a situation like this. Because you matter to us.

Not to worry I'll do everything I can to help get this sorted for you.

Follow the steps below to Troubleshoot a Printer offline status using your Windows computer.

Set the default printer

Set your printer as default on your Windows computer to make sure print and scan jobs use the correct printer.

In Windows, search for and open Printers & scanners.

Make sure the box next to Let Windows manage my default printer is not checked.

From the list of printers, click your printer name, and then click Manage. If there are multiple printer names that match yours, select the printer that is idle or online.

Under Manage your device, click Set as default.

 

Remove and re-add the printer (Windows)

Remove the printer from Windows settings and from the HP Smart app, and then add the printer again.

Search Windows for and open Printers & Scanners, select your printer in the list, and then click Remove device > Yes to complete the removal.

With the printer turned on, click Add a printer or scanner to reinstall the printer.

On the HP Smart app home screen, right-click the printer icon, and then click Hide Printer.

Click Hide Printer again to complete the removal.

Click Add Printer or the plus-sign to re-add the printer.

Create a new printer TCP/IP Port (Windows)

Add a printer port to Windows that matches your printer's IP address.

Print a Network Configuration Report.

HP Smart app: From the app home screen, click the image of your printer, click Printer Reports under Tools, and then select Network Configuration Report.

Printers with a touchscreen control panel: On the control panel, open the Wireless or Network Settings menu, and then select Network Configuration Report or Network Configuration Page.

HP printers without a touchscreen control panel: On the control panel, press and hold the Wireless and Information buttons. Printing reports from the control panel can vary by printer model.

Depending on your printer, another method might be:

Press the Wireless and Resume/Cancel buttons at the same time.

Press and hold the Information button until all buttons light up, and then press and hold the Resume button or press the Information Resume buttons.

Press and hold the Resume button ( or ) until the Ready light blinks.

Find the printer IPv6 address in the 802.11 Wireless section of the report. The address starts with fe80.

In Windows, search for and open Printers & scanners.

Click the name of your printer in the list, and then click Printer properties or Manage > Printer properties.

On the Ports tab, click Add Port.

From the list of available port types, select Standard TCP/IP Port, and then click New Port.

Type the printer IPv6 address, and then click Next.

Select the new Standard TCP/IP Port from the list, and then click OK.

 CAUTION:

You might see two printers in the devices list. Do not remove or uninstall either printer.

Create a manual IP connection

Print a Network Configuration or Wireless Network Test Results Page, and then use the information on it to connect your printer wirelessly.

Print a Network Configuration Report.

HP Smart app: From the app home screen, click the image of your printer, click Printer Reports under Tools, and then select Network Configuration Report.

Printers with a touchscreen control panel: On the control panel, open the Wireless or Network Settings menu, and then select Network Configuration Report or Network Configuration Page.

HP printers without a touchscreen control panel: On the control panel, press and hold the Wireless and Information buttons. Printing reports from the control panel can vary by printer model.

Depending on your printer, another method might be:

Press the Wireless and Resume/Cancel buttons at the same time.

Press and hold the Information button until all buttons light up, and then press and hold the Resume button or press the Information Resume buttons.

Press and hold the Resume button ( or ) until the Ready light blinks.

On the printout, find the Wireless Status, IP Address, Subnet Mask, Default Gateway, and URL.

Wireless status: Under 802.11 Wireless, the Status should be Connected. If it is not, your printer is not connected to the wireless network. Connect your printer to the network. For more information, go to Connect to a wireless HP printer.

IP Address, Subnet Mask, Default Gateway: Under 802.11 Wireless, find the printer's IP Address, Subnet Mask, and Default Gateway numbers. If you see different numbers for IPv4 and IPv6, you only need the IPv4 numbers.

URL(s): Under General Information, find the URL(s) for Embedded Web Server. Your printer might have more than one URL.

From a computer connected to the same network as your printer, open an internet browser, type one of the URLs into the address field, and then press Enter to open the printer's EWS. If the EWS does not display, try another browser.

In the EWS, click the Network or Networking tab, open the Wireless menu option, and then click IPv4 Configuration.

Select Manual IP, and then provide your printer information.

To auto-fill all fields, click Suggest a Manual IP Address, and then make sure the fields for Manual IP Address, Manual Subnet Mask, and Manual Default Gateway match your printer's information on the Network Configuration Page.

If Suggest a Manual IP Address is not available, type the information from the Network Configuration Page into the IP Address, Subnet Mask, and Default Gateway fields.

Click Apply, and then wait until the changes are confirmed.
